A head-mounted display device and a control method thereof, and a computer-readable storage medium are provided. The head-mounted display device includes a display screen and a lens component, and the control method of the head-mounted display device includes: determining gaze directions of both eyes of a user; determining a gaze focus according to the gaze directions of the both eyes; and adjusting positions of the display screen and the lens component according to the gaze focus, so that the gaze focus is located at an image plane position of a virtual image formed by the lens component from an image displayed by the display screen.

Head-mounted display device and control method thereof, computer-readable storage medium

Disclosed is a cross-chain communication method. In this method, a first edge node of a first blockchain receives a first transaction request and validates the first transaction request; on condition that the first transaction request passes the validation, the first edge node will send the first transaction request to a notary node group; the notary node group determines at least one target notary node according to a preset criterion; the at least one target notary node validates the first edge node and a second edge node of a second blockchain corresponding to the first transaction request; and on condition that both the first edge node and the second edge node pass the validation, the first edge node will set up a cross-chain communication with the second edge node depending on the first transaction request to complete a cross-chain transaction. A cross-chain communication device and a storage medium are also disclosed.
